Active Flows and Deformable Surfaces in Development
Sami C. Al-Izzi, Richard G. Morris
We review progress in active hydrodynamic descriptions of flowing media on curved and deformable manifolds: the state-of-the-art in continuum descriptions of single-layers of epith…

Measuring Gaussian rigidity using curved substrates
Piermarco Fonda, Sami C. Al-Izzi, Luca Giomi +1
The Gaussian (saddle splay) rigidity of fluid membranes controls their equilibrium topology but is notoriously difficult to measure. In lipid mixtures, typical of living cells, lin…

Shear-driven instabilities of membrane tubes and dynamin-induced scission
Sami C. Al-Izzi, Pierre Sens, Matthew S. Turner
Motivated by the mechanics of dynamin-mediated membrane tube fission we analyse the stability of fluid membrane tubes subjected to shear flow in azimuthal direction. We find a nove…
